Teen accused of school shooting threat Diamond Ranch High School

Deputies on Monday arrested a 17-year-old Diamond Bar boy for allegedly posting on Twitter a threat to shoot up Diamond Ranch High School. They also confiscated a 22-caliber rifle.

The alleged threat didn’t say when the shooting will occur, according to Lt. Edward Wells of the sheriff’s Walnut/Diamond Bar station. The station found out about the threat around midnight Sunday.

Well said the station got a call from someone who saw on Twitter a picture of a guy holding a rifle and saying he will shoot up the school. Deputies identified the person as a 17-year-old Diamond Bar resident who is a student at the school located at 100 Diamond Ranch Road in Pomona.

Deputies arrested the boy at his home around 1:45 a.m. and recovered a rifle, Wells said. The teen was booked on suspicion of making criminal threats. He is being held at Los Padrinos Juvenile Hall in Downey. Deputies didn’t release his name because he is a minor.

The tweet with the alleged threat couldn’t be found on Twitter by Monday morning. School staff referred the paper to the superintendent’s office for comment.

Fernando Meza, administrative director for pupil and community services at Pomona Unified School District, said deputies contacted school officials Sunday night. He cannot verify yet if the suspect attended Diamond Ranch High School.

The district notified parents and school staff via email and text message that deputies conducted an investigation over comments made on social media, the person involved was taken into custody and it’s safe to be at school today, according to Meza. He said the high school has about 1,800 students.
